SPINDLE.

SPECIFICATION forming part of Letters Patent N o. 768,724, dated August 30, 1904. Application led April l2, 1902. Serial No. 102.543, (No model.)

To @ZZ whom zit may concern,.-

Be it known that I, VICTOR BLANGER, of Seaview, Marshfield, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Spindles, of which the following is a specification.

This invention' has relation to spinning and twisting machinery, and more particularly to the spindles which are employed therein and the mechanism by which power is transmitted from the drum to the spindle-blade.

The spindle is usually equipped with a whirl, around which passes an endless tape, cord, or band driven by a drum or cylinder. The whirl and the drum bear the greatest possible diametrical ratio with relation to each other in order that the spindle may be rotated at the highest speed consistent with a given speed of the drum and the distance between said parts, which is necessarily limited owing to the character of the machine and the space occupied thereby.

It has been found from practical experience that itis not desirable to increase the speed of the drum over a certain number of turns per minute, since by reason of the construction of the drum, its length, and the wear of the bearings the drum causes the vibration of the frame and effects a serious deterioration in the quality and strength of the yarn produced. The vibration of the frame causes the saddle weights to dance, whereby the pressure of the top rolls constantly varies and causes the formation of thick and thin spots in the roving and causes the traveler to move unevenly about the ring, whereby the yarn is unevenly built upon the bobbin and is frequently broken.

The object of the present invention is to provide mechanism by which the speed of the spindle-blade may be materially increased without increasing the speedy of the drum or by which the speed of the drum may be decreased without a corresponding decrease in the speed of rotation of the spindle-blade. In accomplishing this object I remedy the evils which have attended the attempt to increase the production of a frame by an increase in the speed of rotation of the spindles, as hereinbefore described.

The invention consists in certain features of construction and relative arrangement of parts, as recited in the claims, the drawings illustrating and the specification describing one form'of mechanism in which the invention is embodied, but to the details of construction of which the invention is in no wise limited.

On the said drawings, Figure 1 represents in plan view a portion of a spindle-rail with one form of my invention mounted thereon. Fig. 2 representsa front elevation of the same with one of the spindles in section. Fig. 3 represents a section on the line 3 3 of Fig. 2.

The spindle-rail is indicated at t and is apertured at intervals to receive the spindle-casings. Flach spindle consists of a hollow casing flanged, as at to rest upon the rail and threaded, as at b2, to receive a nut c, which coacts with the iiange in clamping it adjustably to the rail. Within the casing is placed a bolster d, and between the reduced lower portion thereof and the. inner wall of the casing is a sleeve-like layer of fibrous material. The lower end of the bolster is held yieldingly against rotation by the usual means, the spindle as thus far described differing in no essential from those now in general use.

The blade is indicated at e, and it has the usual tapering upper and lower ends. It is rotatively mounted in a sleeve f, located between it and the bolster and having a tapering socket to receive said blade. An oil-space. is formed between the ends of the sleeve, and provision is made for the access of oil thereto from the casing, to which oil is supplied from the cup g. The sleeve is adapted to rotate within the bolster, and it projects upward far enough to receive two pulleys f f2, which may be formed integral-ly therewith. If formed separately, said pulleys are secured to said sleeve to rotate therewith.

is attached a whirl or pulley which is less in diameter than either of the pulleys f f2 and which is located directly above them, as shown in Fig. 2.

The pulley f2 receives the tape, cord, or

To the blade v band lf, which is driven by the usual drum or cylinder, l not shown,) and between the pulley f of one spindle and the pulley or whirl e' ot' the next adjacent spindle is stretched a cord or other endless llexible connection Assuming that the ratio ot' the pulleys f and e' are as two to one and that the pulleysf are equal in diameter and are also equal in diameter to the whirl now commonly employed,'it will be apparent that when the drum is rotated at a speed sufficient to rotate the pulleyj3 at nine thousand turns per minute the spindle-blade ot the next adjacent spindle, driven from the pulley j", will be rotated at eighteen thousand turns per minute, or twice the speed attained when the usual construction is followed.

The stoppage ot` one blade in piecing-up7 or in dolling does not retard the rotation of the blade on either side thereof, since the band will slip on the whirl a' thereon, and the pulleysf and f2 are entirely independent thereof. The blade rotates within the sleeve, and the sleeve rotates within the bolster, and they are independent oi' each other. The blade and the sleeve of each spindle are held against accidental axial movement by the latch 7' on the cap 7" ot the oil-cup.

This construction o'l driving mechanism requires the employment oll an extra spindle or an extra pair ot' pulleys f/ at the end of each row ot' spindles; but it does not necessitate an increase in the driving-bands L.

lt desired, the connections e' may be expan' sible and contractile in order to compensate tor adjustment ot' the spindle-casings rela tively to each other.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all ot' the forms in which it may be made or all oli' the modes of its use, I declare that what l cla-im ism l.. vln combination, a rail, a spindle on said rail having' a whirl of relatively small diameter thereon, a driving-band, a rotary member et' relatively large diameter supported on said rail, said rotary member being actuated by said band, and having its axis substantially parallel to the axis ot said spindle, and powertransmitting means between the rotary member and the said whirl in consequence of which the spindle is driven by the rotary member at a relatively higher speed than it driven directly by said band in the usual manner.

' 2. In combination, a rail, a spindle on said rail having a whirl of relatively small diameter thereon, a driving-band, a rotary member of relatively large diameter supported on said rail, said rotary member being actuated by said band, and havingI its a-xis substantially parallel to the axis of said spindle, and a secv ond band connectingI said rotary member and said whirl whereby the latter is driven bythe former at a relatively higher speed than it driven directly by said band.

3. ln combination, a rail, a spindle on said rail having a whirl ot relatively small diameter, a rotary member et relatively larger diameter rotating .said whirl at a higher speed than its own, a driving-band, and a grooved pulley fast with said rotary member and rotating the same, said grooved pulley being not less in diameter than said rotary member.

4. In combination, two casings, a sleeve rotatable in each casing, a blade rotatable in each sleeve, a power-transmitting device connecting the sleeve in one casing with the blade in the other casing.

5. 1n combination, a series ot spindles, each comprising a blade, an independently-rotatable sleeve, and a casing, means t'or rotating each sleeve independently ot' the other sleeves, and a power-transmitting' connection between the sleeve oil one spindle and the blade of the next adjacent spindle.

6. "ln combination, a series ot' spindles, each comprising a blade, an independently-rotatable sleeve, a whirl on the blade and a pair ot' pulleys on the sleeve, a separate band engaging one pulley on each sleeve for rotating it independently of the others, and an endless band connecting vthe other pulley on each sleeve with the whirl on the blade otl the next adjacent spindle.

7. ln combination, a rail, a driving-band, a spindle-Maele,- and speedmultiplying power transmitting mechanism interposed between the said band and the said blade in consequence ot' which the said blade is driven at a speed greater than it' the blade were driven directly by said band, said mechanism ineluding a band-driven member having its axis substantially parallel to the axis olf the blade.

1n testimony whereof l have al'lixed my signature in presence of two witnesses.
